Abstract:
Experimental results on mixed crystals of K 1- x (NH 4 ) x H 2 PO 4 and KH 2 P 1- x As x O 4 are reported as a function of concentration (for x \lesssim0.13) and explained by the modified proton lattice coupled model. Some physical properties of the mixed crystals obtained from measurement of the Curie constants, spontaneous polarizations, and specific heats are related to the role of impurities in the phase transition of the crystals. We found that the interaction energy beween host and impurity is negative for mixed crystal with ADP impurities. This indicates that in this mixed crystal, there is competition between ferroelectric and antiferroelectric exchange interactions.
